Enabling routing globally or on a VRF instance

Use IP forwarding (routing) on a global level so that the device supports routing. You can use the IP address of an interface for IP-based network management.

Procedure

Enter either Global Configuration mode or VRF Router Configuration mode for a specific VRF context:

enable

configure terminal

Optional: router vrf WORD<1-16>
Activate IP forwarding:

ip routing
View the forwarding configuration:

show ip routing [vrf WORD<0–16>] [vrfids WORD<0–512>]

Example

Activate IP forwarding and view the forwarding configuration:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#router vrf green
Switch:1(router-vrf)#ip routing
Switch:1(router-vrf)#show ip routing
